VAPORIZER.

Application filed February 28, 1921. Serial No. 448,583.

To all whom it may concern:

Be it known thatI, JAooB R. SCHMIDT, a citizen of the United States, and a resident of Marion, in the county of Marion and State of Kansas, have invented certain new and useful Improvements in Vaporizers, of which the following is a specification.

My present invention relates generally to Vaporizers and more particularly to a heater for the intake manifold of internal combustion engines whereby to apply vaporizing heat to the fuel passing into the motor through the intake manifold, my object being the provision of a simple manually con trolled and electrically heated arrangement which will be simple and inexpensive in its nature and which will at the same time be durable and highly effective in use.

In the accompanying drawing which illustrates my present invention and forms a part.

of this specification,

Figure 1 is a side view illustrating the practical application of the invention,

Figure 2 is a horizontal section taken on line 22 of Figure 1, and

Figure 3 is a diagram showing the electrical connections and controlling means.

Referring now to these figures I have generally indicated the intake manifold of an internal combustion engine at 10 in Figure 1, with the usual flange 11 ,atone end, for connection by bolts 12 tothe flange 13 of a carbureter pipe 14 through which fuel to the intake manifold 10.

My invention is inthe nature of a body plate 15 as shown in Figure 2, whose outline conforms to the external configuration of the flanges 11 and 13, adapting the body 15, which is fiat, for disposition between these flanges. This body 15 has openings 16 through which bolts 12 ma be extended so that the body can thus be c amped in secure air tight relation between the flanges 11 and 13, with its central opening 17 coinciding with the bores of the pipe 14 and the intake manifold 10.

The body 15 is preferably formed of any suitable insulating material and is entered at diametrically opposite points by contact posts 18, each having an external clamping nut 19. These nuts 19 serve to hold the terpasses The posts 18 constitute the opposite terminals of a heating element preferably in the nature of a wire 24 whose ends are connected to the terminals and which, between its ends, is extended in zig-zag form across the central opening 17 of the body plate 15 around pins 25 and the like of which the body plate has series at opposite sides of its opening.

In practice current may be supplied to the heating element 24 from any suitable point as for instance the ammeter 26 of a motor car as seen in the diagram Figure 3, a feed Wire 27 extending from this ammeter toa manually controlled switch 28, preferably a button switch, located for instance manifold 10.

My invention is thus of a simple, inexpensive nature, is capable of ready inst-allation, includes a readily renewable heating element, and will be vextremely durable in use, and its effectiveness and advantages may be readily apparent, avoiding as it does the necessity of supplying raw gas for starting purposes in cold weather, a practice which whileusually effective is far from desirable on account of flooding the motor and diluting of the lubricating oil by raw gas leaking past the piston rings.

I claim:

A heater consisting of a fiat body formed of a single piece of insulating material having .a central opening with recesses at diametrically opposite points on said openingand also provided along opposite sides of the opening with series of pins projecting beyond one face, contact posts extending into the said body at diametrically opposite points withtheir inner ends projecting into said recesses, a heating element consisting of a wire extending around the pins in zi zag relation across the opening of the b0 y and connected at its opposite ends to the inner ends of the contact posts, and clamping means on the outer portions of the contact posts for the purpose described.

JACOB R. SCHMIDT.
